When you take out the day's garbage to the dumpster you see a homeless woman sleeping inside. So you jump in and fuck the shit out of her and make a big gooey mess all over her with your cum. As you get out yell "Get a job you bum!"
and then throw all of the garbage on her. THIS IS CALLED THE DUMPSTER DUNK!
JIM: Have you seen that hobo bitch that lives in our dumpster?
BOB: Yeah, I just did her ugly and the dumped our trash on her nasty ass.
JIM: Oh-I guess that is why it smells so bad back there, I thought it was a dead animal.
BOB: Nope, just the smell of a DUMPSTER DUNK.
